Locomotive center plate



Jan. 28, 1930. H. K. HARWICK LOCOMOTIVE CENTER PLATE- Filed May 10, 1929 UNITED, STATES PATENT OFFICE HENRY K. HARWICK, F DARBY, PENNSYLVANIA LOCOMOTIVE CENTER PLATE Application filed May 10,

My invention relates to certain improvements in the center plate for a locomotive which is secured to the frame and which is usually located under the cylinder structure.

My present application is a companion to that filed by me on the 2nd day of April,

1929, under Serial No; 351,947, and the object of this invention is to so construct the center plate that it will be adapted to fit in a crossframe which is attached to the side frames of the locomotive and to the cylinder structure.

In the accompanying drawing: Fig. 1 is a transverse sectional view of the center plate; frame; and the cylinder structure, on the line 11, Fig. 2;

Fig. 2 is a sectional plan View on the line 2-2, Fig. 1; and

Fig. 3is a detached center plate. 1

Referring to the drawing, 11 are the side frames of a locomotive made separate and secured to a front frame 2, which, in the present instance, includes the bumper 3, a back frame, and intermediate connecting frames.

The front frame 2 has side members 4.t, which fit between the locomotive side frames 1 and are secured thereto by bolts 5 which in the present instance extend through the perspective view of the vertical webs 6 of the cylinder structure 7.

This structure rests upon the side frames and the front frame as shown in Fig. 1.

The center plate has a cylindrical body portion 8 in the present instance, the upper end of which is in'contact with the underside of the transverse plate 9 of the front frame 2, and as thisplate 9 is in contact with the bottom of the cylinderstructure 7, the center plate has a very substantial support.

Projecting from the base of the body portion 8 of the center plate are four arms 1010 and 11-11. The two arms 1010 extend longitudinally of the locomotive and their turned up ends 12 are secured to like'projections 13 on the front plate by bolts 14;.

The transverse arms 1111 have turned up ends 15 which fit tightly against the side Imembers 4-4 but are not secured thereto by olts.

Webs 16 extend from the cylindrical body 1929. Serial N0. 362,090.v

portion of the center plate to the turned up ends of the arms 1010 and 1111. These webs strengthen the structure. 1

The body center bearing 17 projects fron the bottom of the center plate and rests upon the truck center bearing 18 as shown in Fig. 1.

In order to allow the center plate to fit tightly in the space betweenthe side members 14 of the front plate, the heads of the lower row of bolts that secure the front frame to the side frames are located in countersunk openings.

I claim 1. The combination in a locomotive, of side frames; a front frame connecting the side frames; a center plate extending into the front frame and bearing against the transverse web of said frame, and having trans verse arms fitting tightly against the side members of the front frame, and having arms at front and back secured to said front frame.

2. The combination in a locomotive, of two side frames; a cylinder structure mounted on said frames and having vertical webs located on the outer side of the said frames; a front frame located between the side frames; transverse bolts securing the front frame and the cylinder structure to the side frames; and a center plate located within the front frame and fitting the side walls of the front frame I1Cl1 secured to the front frame at front and 3. The combination in a locomotive, of side frames; a front frame located between the side frames and'having a transverse plate at its upper end; a cylinder structure located on the side frames and in contact with the transverse plate of the front frame; and a center plate located within the front frame at a point under the cylinder structure and having lateral arms tightly fitting against the side members of said front plate, and having upturned ends at front and back, the front plate having upturned lugs to which said arms are secured, the body portion of the center plate bearing against the underside of the transverse plate of the front frame.
